UNITED STATES HARRY BENTZ, OF

NEV YORK, N. Y.

MEDICAL GALVANIC BATTERY.

SPECIFICATION forming part of Letters Application filed November 9, 1899- To ail whom t may concern;

Be it known that l, HARRY BENTZ, of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Galvanic Battery, of which the following is a full, clear, and exact description.

This invention relates to improvements in galvanic batteries adapted to be worn or applied by a person for medicinal purposes; and the object is to provide a device of this character that shall besimple in its construction and having` a simple means whereby the battery or current strength may be easily and quickly changed or regulated.

1 willdescribe a galvanic battery embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters ot' reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of a battery and connections embodying` my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a partial plan and partial section of a pair of cells embodied in the battery. Fig. 4- is a section on the line teef Fig. 3. Fig. 5 is a plan view of one of the battery element-s. Fig. 6 is an end View thereof. Fig. 7 is a plan view of the other element. Fig. S is an end View thereof, and Fig. 9 is a partial section and partial edge view of one of the electrodes employed.

The battery comprises several sets of cells, the cells of each set being connected in series. Fach cell consists of a copper element 1, made in the form of a box open at one end, and a Iinc element 2, arranged within the copper element, and placed between the side surfaces of the plate-like zinc element and the inner surface of the copper element are absorbent pads 3, of felt or similar material, The copper element is provided with perforations 4, through which an exciting fluid may pass to be absorbed by the absorbent pads. This exciting fluid may be vinegar or acidulated water. The zinc element of one cell is connected by means of wires 5 6 with the copper element of the next cell, and the several cells may be held separated from one another by means of strips 7 of rubber or the Patent No. 646,793, dated AprilA s', 190e.

Serial No. 736,351. (No model.)

' like. One set of cells (indicated at a) has the copper element of the first cell connected by means of a wire 8 with a contact-point 9 on a circuit-controller 10. The copper element of the first cell in the next set t is connected by a wire ltwith a contact-point 12 on the circuit-controller, and the copper element of the iirst cell in the next set c is connected by means of a wire 13 with a contact-point 14e on the circuit-controller. The zinc element at the opposite end of each set ot cells is connected by a wire 15 with a binding-post 16, the connections with the Wire 15 being through the wires 17, 18, and'19. It will be noted that there are six cells in each of the battery sets a, b, and c. Other sets 'd and e, however, consist each of two cells. The copper element ot' the first cell in the set l) is connected bya wire 2O with a contact-point 21 on the circuitcontroller, and thel copper element of the first cell in the set c is connected by a wire 22 with a contact-point 23 on the circuit-controller. These two sets d and c have their terminal zinc elements connected by wires 24, 25, and 26 with a binding-post 27. As here shown, the cxtreme end elements are connected by means of metal loops 28 with binding-posts 29, from which the several wires extend. These binding-posts are made in the form of hooks, secured to a base 30, and each has a clamping-screw 31. y

Mounted on the disk 10 to coact with the several contact-points thereon is a segmental plate or circuit-closer 32, and from this plate a wire 33 extends to a binding-post 34. This plate is pivoted on the disk 10 and is of sufiicient area to be placed in engagement with all the contact-points on the disk, so as to close the circuit through all of the batterycells. Also mounted on the disk isa circuitclosing plate 35, made in the form of a segment and adapted for engagement only with the contact-point 23 or with said point 23 and the contact-point 2l, and from this circuitclosing plate 35 a wire 3G extends to a binding-post 37.

In using my invention l employ electrodes 38 39 `so arranged that they may be placed upon any portion of a persons body or head. Each electrode consists of a casing 4.0, of insulating material, within which is arranged a metal plate or disk el, and engaging against IOO e stieg-'res each plate or disk is an absorbent material 42-such, for instance, as sponge. The electrode 38 is connected by a wire 43 with the binding-post 1G, and the electrode 3S) is connected by a Wire 44 with the binding-post 34. For convenience in applying the electrodes I mount them in an adjustable frame consisting of longitudinally-slotted bow-plates 45 46, these plates being connected, respectively, at one end to a hub portion on the electrodes 3S 39,an d they are adjustable on a U -shaped longitudinally-slotted plate 47, and they are held as adjusted relatively tothe plate 47 by means of set-screws 48 49, the set-screw 4S passing through the plates 45 and 47 and the set-screw 49 passing through the plates 4G and 47. These several plates are of spring-yielding material, and obviously by their use and construction the electrodes may be moved toward 0r from each other toaccommodate them to a persons head, arm, leg, or the like.

In operation the battery and the circuit-controller may be placed upon a belt to be Worn by a person; but Ido not conne my invention t0 thus mounting the parts, as it is obvious that the battery and circuit-controller may be placed quite remote from each other or arranged in a suitable case, the electrodes being free for movement from place to place. Should a Weak current be desired or that from a single set of cells, the plate 32Will be turned into engagement with the contact-point 9, thus utilizing the current from the set of cells d. Should a stronger current be desired, the plate will be turned into engagement with the contacts 9 and l2, thus utilizing the current from the two sets of cells a b, and obviously when the plate is turned into engagement With all of the contact points the strength of the entire battery will be passed through the electrodes and through the body of a person in contact with the electrodes and serving as a circuit-closer between the electrodes.

By means of the binding-posts 27 and 37 another set of electrodes may be employed, if desired, and energized either from the set of cell elements e upon turning the plate 35 into engagement with the contact-point 23 o r from both the sets of cells d and @by turning said plate 35 into engagement with the contact-points 28 and 2l.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- Il A medicinal galvanic battery, co1nprising a number ol" sets of cells all mounted on a single support, the cells ol each set being connected in series, a circuit-closer for controlling a circuit lthrough one or all of said sets of cells, and anotherl circuit-controller for closing the circuit through one or two of said sets of cells independently of the other cells, substantially as specified.

2. A medicinal galvanie battery, comprisin ga number of sets of cells,a circuit-controller comprising a disk, contact-points on said disk having connection with the various sets of cells, a eircuit-closing plate mounted to rotate .on said disk and adapted for engagementwith all of the contact-points, and another circuitclosing plate mounted to rotate on said disk and adapted for closing the circuit through two of said sets of cells, substantially as specified.
